AN ANALYSIS OF NIGERIAN SAVANNA: ORDINATION OF VEGETATION DEVELOPED ON DIFFERENT PARENT MATERIALS.

The article presents an environmental analysis of the savanna vegetation in Northern Nigeria. The study indicates that soil parent material is not a major factor in the arboreal vegetation of an area. It reveals that the main factors are the water availability in the soil and the degree of human interference. The factors control the general ordination of both noda and groups, soil water and human interference. Moreover, the general case differences in soil parent material do not necessarily imply differences in the arboreal vegetation.
